The book trailer is just beginning to find its voice. As the name suggests, the book trailer is a video that promotes a book, much as a movie trailer generates hype for its feature film. Two years ago, a clip was released for Thomas Pynchon's eagerly awaited Inherent Vice. In the trailer, notably voiced by the reclusive author himself, shaky video footage of barren California beaches and a soundtrack reminiscent of Pink Floyd gives the narration a nostalgic feel. At the end, Pynchon all but tells you to stop watching: Maybe you'll just want to read the book, before balking at its retail price.
